The Fox-body Mustang is undoubtedly becoming one of the most popular Fords of all time, and the abundance of aftermarket components is its main attraction. Every aspect of the ’79-’93 Mustang is upgradeable, and whether you want a killer street car or an all-out drag car, the Fox-body Mustang proves to be a great platform for all kinds of performance goals. B.C. Happach of Pekin, Illinois, recognized this great potential and bought a ’91 Mustang hatchback back in March 1996. Small upgrades here and there, including a NitrousWorks plate kit, gave Happach a street-friendly Mustang that consistently ran in the high 12s with the stock suspension.
When you go looking to make huge power from your 5.0-liter Ford, the limiting factor will always be the weakest link in the chain. In the case of our supercharged 331 stroker buildup, the weakest link turned out to be the production block. Like most enthusiasts, we had no budget for a DART racing block or even a Ford Racing Sportsman block, but we decided to tempt fate nonetheless and go for a big power number on the dyno. Considering that the stock fuel-injected 5.0-liter was rated at a measly 225 hp, even a 300hp buildup would offer a welcome change in performance.
While the small-block Chevy is the popular engine choice for many enthusiasts, many are now relying on a Blue Oval heart for their performance bodies. With its link to Ford, the original body manufacturer for many of the classic cars we see today, the small-block Windsor-style Ford engine offers several advantages. When compared to Chevy, the lack of firewall clearance for a number of Chevy engine swaps is due to the rear distributor position of the engine. The front-mount distributor position is the more logical place to drive the distributor and the oil pump. Not to mention, it’s much more convenient.
